Question

please solve problem #2 and explain

(30p) For the transistor bias network below: a) identify the type of transistor b) identify all terminals 12v c) label all typical transistor voltages and currents 430kΩ 24k Ω W 5 λ=0 The arrow at the transistor goes out at the bottom terminal 200kΩ 47ks2 #2. (25 p-For the transistor network from problem i, draw the v-diagram (3-5 v curves) and find the Q-point using the load line analysis. Compare with the results of problem

Answer 1

Given that a) we have to identity type of transfer from the above ekt we see the transistor from the above transistor arrow causes out so it is N mos transistor V_CE is indicated as gate voltage V_D is indicated as drawn voltage vs is indicated as source voltage here drawn current is I_D gate current = I_G = OA if gate I_r = OA [No current flows gate] (C) we have to calculate typical transistor voltage currents voltage at the gate terminal V_r = V_m 2 infinity k Ohm/200 k ohm + 450 k ohm Vm = 12 v implies 12 v 200/630 2400/630 V_4 = 3.80 v voltage across gate region v_g = 80/21 v = 1v from the ckt diagram voltage across sources region R_s = 47 k ohm current flow through it is ID V-s = 47 k ohm times I_D voltage across drawn terminal is indicated as V_D therefore V_D = 12 v - (24 kkD)
